SHEET SEPARATING AND PRINTING MACHINE.

SPECIFICATION forming part of Letters Iatent No. 525,999, datedSeptember 11, 1894.

Application filed December 26, 1893. Serial No. 494,813. (No model.)

To all whom it may concern-.-

Be it known that I, CASPER REISING, acitinon of the United States,residing at Southlngton, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in SheetSeparating tnd Printing Machines, of which the followng is a full,clear, and exact specification.

This invention relates to mechanism for automatically separating andfeeding paper bags, envelopes, or sheets of paper from a wile to thecylinder or platen of a printing )ress, and to mechanism for removingthem v rom that cylinder and delivering them in a die after beingprinted.

, Figures 1, 2, and 3 of the drawings are genral views of a machineembodying my inention, showing also enough of the neces- ;ary and usualmechanism of an ordinary printing press to enable its connection andco-operation therewith to be understood; and are respectively a front,an end and a rear View thereof. Those figures also show the ink feedingmechanism fully. Fig. 4 is an enlarged front View of the upper portionof the mechanism, showing the details more fully. Fig. is a projectionat an angle of forty-five degrees, of a portion of what is shown in Fig.4. Fig. 6 is a view looking from the right hand side of Fig. 4. Figs. 7and 8 are diagrammatic views, partly in section, showing the operationof registering and delivering a sheet from the box to the cylinder. Fig.9 is a side View in section taken on the line 9-9 of Fig. 6. In thisfigure the parts are shown in the position in which the port 61 of thetake of roll registers with the port 64 in the vacuum box 62, and inwhich the sheet is taken off from the cylinder 22. I

The numerals 1 and 2 represent the principal frames of a printingmachine, upon which the bed 3 is adapted to move back and forth,carrying the type form from which the sheets are to be printed. The bedis reciprocated by a crank shaft 4 by means of theconnecting rod 5,which is connected by the pin 5 to the lever 6. That lever is pivotedupon the shaft 7 and has journaled on its upper end the box 8 which isfitted to slide in aslot in the platen 3. The form isinked by thedistributing rollers 14, which receive the ink from the ink reservoir9'. Thatreservoir is pivoted at 10 upon the frames 1 and 2 and is causedto oscillate upon its pivots by means of the connecting rod 11 from thecrank pin 12 in the side of the gear 13, as shown in Fig. 1. Thefountain is provided with the ink roll 15, by means of which ink is fedto the nearest of the distributing rollers 14, when they are broughtinto contact by the oscillation of the fountain. That oscillation of thefountain also causes the ink roller to be slowly rotated by means of itsratchet wheel 16 fixed to the roll shaft and the pawl 17 pivoted on thearm 18, which is connected by the rod 19 to the main frame at 20. As thefountain is oscillated forward toward the distributor rollers the pawlarm is also pushed forward, by the rod, the pawl passes over one or moreteeth on the ratchet, and on the backward stroke the ratchet and its inkroll are advancedacorrespondingamount. Theamount of. angular rotation ofthe roll at each stroke may be varied by altering the position of theconnecting pin in the pawl arm 18. The rollers 21 are also employed toinsure a more thorough distribution of the ink upon the form.

The impression cylinder 22 is journaled upon the eccentric part 23' ofthe cylinder shaft 23, and is provided with the gear 24 which engageswith a rack 25 on the bed 3, by which the gear andits attached cylinderare caused to oscillate as the bed is moved back and forth. The relationof the rack and gear is such that the surfaces of the cylinder and thebed move at the same speed. The shaft 23 is journaled in the brackets 26and 27 and has fixed upon its rear end the arm 28 which is connectedwith the cam 29 on the crank shaft 4 by means of the rod 30 and thelever 31, the latter being pivoted at 32 to the main frame 2. The lever31 is held in contact with the cam 29 by the spring 33, and that camoperates through its connection with the shaft 23 to cause that shaft tooscillate at suitable times for the purpose of lowering the cylinderinto suitable contact with the type when a sheet is being printed, andalso for the purpose of oscillating the cam 39 as herinafter specified.

The cylinder is provided with a recess 34 in which is located a gripper35 having its outer end adapted to hold the bags or sheets upon theperiphery of the cylinder. That grlpper is fixed upon the end of a shaft36, which is journalcd in the cylinder and has fixed on its other endthe cam arm 37. The spring 38 is attached to the cylinder and to the camarm and operates to press the gripperdown upon the cylinder. Theadjustable registering stops 41 and 42 are attached to the cylinder, toregulate the register of the bags thereon. The cam 39is fixed on theshaft 23 and operates to open the gripper 35 at a suit able time toreceive the sheet, and a cam sur face 011 the bracket 26 is adapted toopen the gripper at a suitable time for releasing the sheet from thecylinder as it is transferred to the take-off roll. 45.

The take-oft roll 45 is fixed on the shaft46, which is journalcd in thebrackets 26 and 27. The gear 47 is fixed on the shaft 46 and meshes withthe rack 48 which is connected by its stem to the crank pin 52 on theslotted crank 50, which is fixed on the shaft 4 by a set screw The rack48 is fitted to slide through the guide 51, which, by being journaled onan extension of the bracket 27 concentric with the shaft 46 is adaptedto keep the rack in engagement with its gear 47 as the rack is moved bythe crank 50. The take-off roll is provided with a recess in itsperiphery in which is located the gripper 53 fixed on the shaft 54, theouter end of that shaft having fixed upon it the cam arm 55, whichisheld in engagement with the cam 56 by the action of the spring 57attached to the arm and to a stud on the take-01f roll. The cam 56 isattached to the bracket 26, concentrically with the shaft 46, forconvenience in adjusting to position,

- and its function is to operate the gripper 53 for exhausting the airtherefrom.

at suitable times to grip the sheet to the roll 45, and to release ittherefrom in order that it may fall into the box 58. The roll 45 isprovided with an internal chamber having two external openings, 60 and61, the former being close by the gripper 53, and the latter so locatedas to communicate with the adjacent port 64 in the vacuum box 62, whenthe roll 45 is in position to receive the sheet from the cylinder 22, asshown in Fig. 9.

The vacuum box 62, is supported on the brackets 26 and 27 and isconnected by a tube 63 with any of the various known means A portion ofthe box 62 is fitted to the roll 45, and has a port 64 whichcommunicates with the opening 61 in the roll 45, when the latter isoscillated to its position therefor. Thus that roll operates asavalve toallow of the alternate admission and exhaustion of air to and from itsinterior chamber. One end of the vacuum box also extends over thecylinder 22, and has an opening adjacent thereto for the purposehereinafter specified. The top of the vacuum box is used as a-table orsupport for the sheets to be fed to the machine, and is preferablysomewhat steeply inclined in order that the weight of the sheets maykeep them well against the lower or gaging end. Upon the vacuum box arealso fitted the side pieces 65 and 66, forming a sort of box in whichthe sheets are placed. These sides are adjustable toward and from eachother to suit the various widths of sheets,and are fastened in theirplaces by bolts as at 67. Upon the lower ends of these box sides arefastened the L-shaped gaging pieces 68 and 6.), against which the lowerends of the sheets rest, as shown in Figs. 7 and 8. To the cross brace70 is fastened the guard plate 71, the lower members of which partlyencircle the cylinder, to keep the sheets from the inking rollers. Uponthe upper end of the guard plate, or to any convenient support, isattached the adjustable stop finger 7 2, one end of which projectswithin the plane of the gage pieces 68 and 69 to an extent which may beregulated by the stop screw 73 as shown in Fig. 4. The position of thisfinger and its use in the operation of feeding the sheet, are best shownin Figs. 7 and 8, wherein is also shown in cross section the vacuum boxwith a pile of sheets in position to be fed to the cylinder. The lowerleft hand end of that box, as seen in the last mentioned figures is madeat an angle with its upper surface on which the sheets rest, so as toallow the lower end of the bottom sheet to bend downward into contactwith the cylinder, the sheet being therefore unsupported beyond the edge59 of the box, excepting by the stop finger 72. An opening 74 into thevacuum box is so located in this lower inclined end as to allow thesuction to operate upon the unsupported part of the sheet to bend itdown as shown in Fig. 8.

The operation of the machine is as follows: A form, carrying type forthe matter to be printed on the sheets, is secured to the bed, and theusual steps of making ready are taken. The sheets are placed upon thevacuum box, and the sides 65 and 66 and gage pieces 68 and 69 areadjusted for the proper registration of the sheets upon the cylinder, sothat one end of the pile is supported by the vacuum box while the edgeof the overhanging end is supported by the stop finger 72. Communicationbetween the vacuum box and the means for exhausting the air therefrom,is opened by means of a slide in the pipe 63, and power is applied tothe mechanism in the usual way, causing the bed to reciprocate, andoscillating the cylinder and the take-off roll. The air rushing towardthe opening 74 operates to draw down the lower end of the undermostsheet toward that opening, curving and thus drawing back the lower endas shown in Fig. 7 until its edge is drawn clear of the stop finger 72,and falls upon the cylinder 22, as shown in Fig. 8. At this time thatcylinder has nearly completed its backward oscillation in the directionof the arrow 75, and its gripper 35 is raised by the action of its arm37 against the cam 39, which is IIO brought forward to meet that arm bya slight oscillation of the shaft 23. Just before the cylinder reachesthe limit of its oscillation in the direction of the arrow 75 theregistering stops 41 and 42 are brought against the front edge of thesheet, thus insuring more perfect registration. Then the shaft 23 isoscillated slightly, so as to carry the cam 39 away from the gripperarm, allowing the gripper to drop upon the sheet, and hold it to thecylinder, which then oscillates in the direction of the arrow 76,drawing the sheet out of the box and carrying it around into contactwith the type, the shaft 23 being 0scillated to allow of a suitableimpression. The cylinder continues to oscillate in this directlon untilthe leading end of the sheet reaches the point nearest in contact withthe take-off roll 45 when the gripper 35 is raised by the cam 40, thesheet is released from the cylinder, and is transferred to the take-offroll, as shown in Fig. 9. The oscillations of the take-off roll are sotimed as to bring the opening and the gripper 53 into a positionrelative to the cylinder which best allows of receiving the front end ofthe sheet therefrom. In that position the gripper 53 is raised by thecam 56, and the opening 61 communicates with the port 6% in the vacuumbox, so that the resulting how of air toward the opening 60 operates tocarry the leading end of the sheet against the roll as it is releasedfrom the cylinder by the gripper 35. The take-off roll is thenoscillated in the direction of the arrow 77, allowing the gripper 53 todrop upon the sheet, which is then carried by the eontinuedoscillationof the roll to a suitable point for delivering it to the box 58. Duringthis oscillation-the opening 61 is carried out of communication with theport 64: in the vacuum box, and the normal atmospheric pressure isrestored within the roll, so that the sheet is free to drop from theroll when the gripper 53 is raised by its cam 56. Having delivered thesheet to the takeoff roll, the cylinder returns in the direction of thearrow 75 to its position for receiving the next sheet, being raised toclear the bed during that return by the action of the cam 29 and theeccentric shaft 23. The takeoff roll, having delivered the sheet to thebox, returns to its first position in time to receive the next sheetfrom the cylinder. Thus it will be seen that the cylinder and thetakeoff roll are caused to oscillate in the same direction substantiallyat the same time, and it is obvious that the latter might receive itsmotion from the former by means of suitably proportioned intermediategears meshing with the gear 24 and the gear 47, without departing fromthe substance and eifect of this invention; but I prefer the mode hereinshown for operating the take-off roll, as I am thereby better enabled toregulate the angular extent and time of the oscillations thereof byadjustment of the pin 52 in the slotted vcrank, and by the adjustment ofthat crank upon itsshaft t.

It is not an essential feature of this invention that the communicationbetween the vacuum box and the take-off roll shall beat the periphery ofthat roll, as it may with equal advantage be located on the side or endth reof. Nor is it my intention to limit myself to the precise means ofcommunication herein shown between the arm 28 and its cam 29, as it isobvious that any of the well known connections may be employed, or thatthe cam may be so located with reference to the arm as to allow thelatter to work directly upon the cam without theintervention of anyconnection Whatever; but I have preferred to avoid the addition of arevolving shaft and its connections, as would be required by such amethod and have located my cam uponthe principal main shaft of themachine, believ- .ing this arrangement to be more direct and simple,

It is not essential that the take-off roll shall be cylindrical in form,as its function is in no way dependent upon that form. It IS hereinshown as a cylinder for ease of contruction, and because that form iseasily balanced. In many similar ways the various elements of thisinvention may be modified, or equivalent elements substituted, withoutdeparting from the spirit and substance thereof.
